Bahamut

Many dragons speak
of the ancient dragon-gods with nothing but reverence, but those that know of
the legend of Bahamut cannot avoid the presence of corruption in draconic
society of the past. Bahamut was said to be the most beautiful and powerful
dragon alive in those days, but not even his opposition to the creation and
summoning of the Comet could prevent the inevitable. Disgusted with his
kindred, and planning for the devastation that would follow the coming of the
Comet, Bahamut withdrew from the planet of IIo to come back when there would be
need. The Ursa revere Bahamut as the Guardian of the Realm of Cosmos and Ruler
of the Above.
